Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

U.S. state
–
A U. S. state is a constituent political entity of the United States of America. There are 50 states, which are together in a union with each other. Each state holds administrative jurisdiction over a geographic territory. Due to the shared sovereignty between each state and the government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders. States range in population from just under 600,000 to over 39 million, four states use the term commonwealth rather than state in their full official names. States are divided into counties or county-equivalents, which may be assigned some local authority but are not sovereign. County or county-equivalent structure varies widely by state, State governments are allocated power by the people through their individual constitutions. All are grounded in principles, and each provides for a government. States possess a number of powers and rights under the United States Constitution, Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the government playing a much larger role than it once did. There is a debate over states rights, which concerns the extent and nature of the states powers and sovereignty in relation to the federal government. States and their residents are represented in the federal Congress, a legislature consisting of the Senate. Each state is represented in the Senate by two senators, and is guaranteed at least one Representative in the House, members of the House are elected from single-member districts. Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census, the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50, alaska and Hawaii are the most recent states admitted, both in 1959. The Constitution is silent on the question of states have the power to secede from the Union. Shortly after the Civil War, the U. S. Supreme Court, in Texas v. White, as a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance

The United States Census Bureau estimates that the population of Colorado was 5,540,545 on July 1,2016, the state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy silt the river carried from the mountains. The Territory of Colorado was organized on February 28,1861, Colorado is nicknamed the Centennial State because it became a state in the same year as the centennial of the United States Declaration of Independence. Colorado is noted for its landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers. Denver is the capital and the most populous city of Colorado, residents of the state are properly known as Coloradans, although the term Coloradoan has been used archaically and lives on in the title of Fort Collins newspaper, the Coloradoan. Colorado, Wyoming and Utah are the states which have boundaries defined solely by lines of latitude and longitude. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado, Colorado is the only U. S. state that lies entirely above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County, Colorado and this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than one half of the area of Colorado is flat, East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from roughly 3,350 to 7,500 feet. The Colorado plains were mostly prairies, but they have many patches of forests, buttes. Eastern Colorado is presently covered in farmland and rangeland, along with small farming villages. Precipitation is fair, averaging from 15 to 25 inches annually, corn, wheat, hay, soybeans, and oats are all typical crops, and most of the villages and towns in this region boast both a water tower and a grain elevator. Irrigation water is available from the South Platte, the Arkansas River, and a few other streams, however, heavy use of ground water from wells for irrigation has caused underground water reserves to decline. As well as agriculture, eastern Colorado hosts considerable livestock, such as cattle ranches. Roughly 70% of Colorados population resides along the edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne, Wyoming, and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado. The Front Range includes Denver, Boulder, Fort Collins, Loveland, Colorado Springs, Pueblo, Greeley and other townships, on the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction, Durango, and Montrose

Municipal corporation
–
A municipal corporation is the legal term for a local governing body, including cities, counties, towns, townships, charter townships, villages, and boroughs. Municipal incorporation occurs when such municipalities become self-governing entities under the laws of the state or province in which they are located, often, this event is marked by the award or declaration of a municipal charter. A city charter or town charter is a document establishing a municipality such as a city or town. The concept developed in Europe during the Middle Ages and is considered to be a version of a constitution. Traditionally the granting of a charter gave a settlement and its inhabitants the right to town privileges under the feudal system, townspeople who lived in chartered towns were burghers, as opposed to serfs who lived in villages. Towns were often free, in the sense that they were protected by the king or emperor. Today the process for granting charters is determined by the type of government of the state in question, in monarchies, charters are still often a royal charter given by the Crown or the state authorities acting on behalf of the Crown. In federations, the granting of charters may be within the jurisdiction of the level of government such as a state or province. In Brazil, municipal corporations are called municípios and are created by means of legislation at the state level. All municipal corporations must also abide by a municipal law which is passed and amended at the municipal level. In Canada charters are granted by provincial authorities, in Germany, municipal corporations existed since antiquity and through medieval times, until they became out of favour during the absolutism. In order to strengthen the spirit, the city law of Prussia dated 19 November 1808 picked up this concept. It is the basis of municipal law. In India, a Municipal Corporation is a local government body. This standard varies from state to state, according to laws passed by state legislatures, the Corporation of Chennai was the first Municipal Corporation in India. It was established on 29 September 1688 by the British East India Company, the second was Hyderabad Municipal Corporation established in 1869 by the Nizam rulers of Hyderabad State. The third was the Calcutta Municipal Corporation, established in 1876, the Bombay Municipal Corporation was established in 1888 by the Bombay Municipal Corporation Act. The Delhi Municipal Council was established in 1911 during the Delhi Durbar when New Delhi was proclaimed to be the new Capital of India and it was elevated to Municipal Corporation level on 7 April 1958 by an Act of Parliament which established the Municipal Corporation of Delhi

2010 United States Census
–
The 2010 United States Census, is the twenty-third and currently most recent United States national census. National Census Day, the day used for the census, was April 1,2010. As part of a drive to increase the accuracy,635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed, participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25,2010, Census Bureau Director Robert Groves personally inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, more than 120 million census forms were delivered by the U. S. Post Office beginning March 15,2010, the number of forms mailed out or hand-delivered by the Census Bureau was approximately 134 million on April 1,2010. The 2010 Census national mail participation rate was 74%, from April through July 2010, census takers visited households that did not return a form, an operation called non-response follow-up. In December 2010, the Census Bureau delivered population information to the president for apportionment, personally identifiable information will be available in 2082. The Census Bureau did not use a form for the 2010 Census. In several previous censuses, one in six households received this long form, the 2010 Census used only a short form asking ten basic questions, How many people were living or staying in this house, apartment, or mobile home on April 1,2010. Were there any additional people staying here on April 1,2010 that you did not include in Question 1, mark all that apply, Is this house, apartment, or mobile home – What is your telephone number. What is Person 1s age and Person 1s date of birth, is Person 1 of Hispanic, Latino, or Spanish origin. Does Person 1 sometimes live or stay somewhere else, the form included space to repeat some or all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey. The survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years. A small percentage of the population on a basis will receive the survey each year. In June 2009, the U. S. Census Bureau announced that it would count same-sex married couples, however, the final form did not contain a separate same-sex married couple option

Mountain Time Zone
–
The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the specification for the location of time zones. In the United States and Canada, this zone is generically called Mountain Time. Specifically, it is Mountain Standard Time when observing standard time, the term refers to the fact that the Rocky Mountains, which range from northwestern Canada to the US state of New Mexico, are located almost entirely in the time zone. In Mexico, this zone is known as the Pacific Zone. In the United States and Canada, the Mountain Time Zone is one ahead of the Pacific Time Zone and one hour behind the Central Time Zone. Sonora in Mexico and most of Arizona in the United States do not observe daylight saving time, and during the spring, summer, and autumn months they are on the same time as Pacific Daylight Time. The Navajo Nation, most of which lies within Arizona, does observe DST, although the Hopi Nation, as well as some Arizona state offices lying within the Navajo Nation, the largest city in the Mountain Time Zone is Phoenix, Arizona. TV broadcasting in the Mountain Time Zone is typically tape-delayed one hour, sonora – no daylight saving time, always on MST. Sinaloa Revillagigedo Islands, three of the four islands have the time as Mountain Time Zone, Isla Socorro, San Benedicto Island. The following states or areas are part of the Mountain Time Zone, Arizona – no daylight saving time, always on MST, except on the Navajo Nation. Colorado Idaho – southern half, south of the Salmon River Kansas – only the counties of Sherman, Wallace, Greeley and Hamilton, the remaining three counties that border Colorado, Cheyenne, Morton and Stanton, observe Central Time, as do all other Kansas counties. However, the state of Oklahoma is officially in the Central Time Zone. Additionally, northwestern Culberson County, Texas unofficially observes Mountain Time

Daylight saving time
–
Daylight saving time is the practice of advancing clocks during summer months by one hour so that evening daylight lasts an hour longer, while sacrificing normal sunrise times. Typically, regions that use Daylight Savings Time adjust clocks forward one hour close to the start of spring, American inventor and politician Benjamin Franklin proposed a form of daylight time in 1784. New Zealander George Hudson proposed the idea of saving in 1895. The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30,1916, many countries have used it at various times since then, particularly since the energy crisis of the 1970s. The practice has both advocates and critics, DST clock shifts sometimes complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns. Computer software often adjusts clocks automatically, but policy changes by various jurisdictions of DST dates, industrialized societies generally follow a clock-based schedule for daily activities that do not change throughout the course of the year. The time of day that individuals begin and end work or school, North and south of the tropics daylight lasts longer in summer and shorter in winter, with the effect becoming greater as one moves away from the tropics. However, they will have one hour of daylight at the start of each day. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, DST is also of little use for locations near the equator, because these regions see only a small variation in daylight in the course of the year. After ancient times, equal-length civil hours eventually supplanted unequal, so civil time no longer varies by season, unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies. This 1784 satire proposed taxing window shutters, rationing candles, and waking the public by ringing church bells, despite common misconception, Franklin did not actually propose DST, 18th-century Europe did not even keep precise schedules. However, this changed as rail transport and communication networks came to require a standardization of time unknown in Franklins day. Modern DST was first proposed by the New Zealand entomologist George Hudson, whose shift work job gave him time to collect insects. An avid golfer, he also disliked cutting short his round at dusk and his solution was to advance the clock during the summer months, a proposal he published two years later. The proposal was taken up by the Liberal Member of Parliament Robert Pearce, a select committee was set up to examine the issue, but Pearces bill did not become law, and several other bills failed in the following years. Willett lobbied for the proposal in the UK until his death in 1915, william Sword Frost, mayor of Orillia, Ontario, introduced daylight saving time in the municipality during his tenure from 1911 to 1912. Starting on April 30,1916, the German Empire and its World War I ally Austria-Hungary were the first to use DST as a way to conserve coal during wartime, Britain, most of its allies, and many European neutrals soon followed suit. Russia and a few other countries waited until the year

ZIP code
–
ZIP Codes are a system of postal codes used by the United States Postal Service since 1963. The term ZIP, an acronym for Zone Improvement Plan, was chosen to suggest that the travels more efficiently, and therefore more quickly. The basic format consists of five numerical digits, an extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code. The term ZIP Code was originally registered as a servicemark by the U. S. Postal Service, USPS style for ZIP is all caps and the c in code is also capitalized, although style sheets for some publications use sentence case or lowercase. The early history and context of postal codes began with postal district/zone numbers, the United States Post Office Department implemented postal zones for numerous large cities in 1943. For example, Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis 16, by the early 1960s a more organized system was needed, and on July 1,1963, non-mandatory five-digit ZIP Codes were introduced nationwide. Three months later, on October 1,1963, the U. S, an earlier list in June had proposed capitalized abbreviations ranging from two to five letters. The abbreviations have remained unchanged, with one exception, according to the historian of the U. S. Robert Moon, an employee of the post office, is considered the father of the ZIP Code, he submitted his proposal in 1944 while working as a postal inspector. The post office gives credit to Moon only for the first three digits of the ZIP Code, which describe the sectional center facility or sec center, an SCF is a central mail processing facility with those three digits. The SCF sorts mail to all post offices with those first three digits in their ZIP Codes, the mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. The United States Post Office used a character, which it called Mr. ZIP. He was often depicted with a such as USE ZIP CODE in the selvage of panes of stamps or on labels contained in, or the covers of. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4, often called plus-four codes, add-on codes, or add ons. But initial attempts to promote use of the new format met with public resistance. For Post Office Boxes, the rule is that each box has its own ZIP+4 code. However, there is no rule, so the ZIP+4 Code must be looked up individually for each box. It is common to use add-on code 9998 for mail addressed to the postmaster,9999 for general delivery, for a unique ZIP Code, the add-on code is typically 0001

Geographic Names Information System
–
It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names to promote the standardization of feature names, the database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited, variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a permanent, unique feature record identifier, sometimes called the GNIS identifier, the database never removes an entry, except in cases of obvious duplication. The GNIS accepts proposals for new or changed names for U. S. geographical features, the general public can make proposals at the GNIS web site and can review the justifications and supporters of the proposals. The Bureau of the Census defines Census Designated Places as a subset of locations in the National Geographic Names Database, U. S. Postal Service Publication 28 gives standards for addressing mail. In this publication, the postal service defines two-letter state abbreviations, street identifiers such as boulevard and street, department of the Interior, U. S. Geological Survey, National Mapping Division, Digital Gazeteer, Users Manual.

County seat
–
A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China, in the United Kingdom and Ireland, county towns have a similar function. In the United States, counties are the subdivisions of a state. Depending on the state, counties may provide services to the public, impose taxes. Some types of subdivisions, such as townships, may be incorporated or unincorporated. The city, town, or populated place that houses county government is known as the seat of its respective county, a county seat is usually, but not always, an incorporated municipality. The exceptions include the county seats of counties that have no incorporated municipalities within their borders, such as Arlington County, Virginia, likewise, some county seats may not be incorporated in their own right, but are located within incorporated municipalities. For example, Cape May Court House, New Jersey, though unincorporated, is a section of Middle Township, in some of the colonial states, county seats include or formerly included Court House as part of their name. Most counties have only one county seat, an example is Harrison County, Mississippi, which lists both Biloxi and Gulfport as county seats. The practice of multiple county seat towns dates from the days when travel was difficult, there have been few efforts to eliminate the two-seat arrangement, since a county seat is a source of pride for the towns involved. There are 36 counties with multiple county seats in 11 states, Coffee County, for example, the official county seat is Greensboro, but an additional courthouse has been located in nearby High Point since 1938. For example, Clearwater is the county seat of Pinellas County, Florida, in New England, the town, not the county, is the primary division of local government. Historically, counties in this region have served mainly as dividing lines for the judicial systems. Connecticut and Rhode Island have no county level of government and thus no county seats, in Vermont, Massachusetts, and Maine the county seats are legally designated shire towns. County government consists only of a Superior Court and Sheriff, both located in the shire town. Bennington County has two towns, but the Sheriff is located in Bennington. In Massachusetts, most government functions which would otherwise be performed by county governments in other states are performed by town governments. As such, Massachusetts has dissolved many of its county governments, two counties in South Dakota have their county seat and government services centered in a neighboring county

Lucius Quintus Cincinnatus Lamar II
–
Lucius Quintus Cincinnatus Lamar II was an American politician and jurist from Mississippi. S. Lamar was born at the home of Fairfield, near Eatonton, Putnam County, Georgia. He was a cousin of future associate justice Joseph Lamar, and nephew of Mirabeau Buonaparte Lamar, in 1845 he graduated from Emory College, then located in Oxford, Georgia. He was a member of Sigma Alpha Epsilon fraternity and was among the first initiates in that fraternitys chapter at the University of Mississippi, after graduating, Lamar married the daughter of Augustus Baldwin Longstreet, one of the University of Mississippis early presidents. In 1849, Lamars father-in-law, Professor Longstreet, moved to Oxford, Lamar followed him and took a position as a professor of mathematics for a single year. He also practiced law in Oxford, eventually taking up the role of a planter, establishing a plantation named Solitude in northern Lafayette County. In 1852, Lamar moved to Covington, Georgia, where he practiced law and he became involved with the Democratic Party and in 1853, he was elected to the Georgia State House of Representatives. In 1855, Lamar moved with his back to Mississippi. He was elected to the U. S. House of Representatives in 1856, beginning his service in 1857. When Mississippi seceded from the Union and joined the Confederacy on January 9,1861, Lamar said, Thank God, we have a country at last, to live for, to pray for, and if need be, to die for. Lamar retired from the House in December 1860 to become a member in the Mississippi Secession Convention, Lamar drafted the states Ordinance of Secession. He considered a staff appointment to the new government, but abandoned that to co-operate with his law partner, Christopher H. Mott in raising and supplying a regiment. Lamar raised, and funded out of his own pocket, the 19th Mississippi Infantry Regiment, Mott was commissioned colonel, as he had served as an officer in the war with Mexico, and Lamar was commissioned as lieutenant colonel. Lamar resigned his professorship in the university and was, on May 14, in Montgomery, on May 15,1862, Colonel Lamar, while reviewing his regiment, fell with an attack of vertigo, which had previously disabled him, his service as a soldier was ended. After this he served as an advocate, and aide to his cousin. Later in 1862, Confederate States President Jefferson Davis appointed Lamar as Confederate minister to Russia and special envoy to England, when the Civil War was over, he returned to the University of Mississippi where he was a professor of metaphysics, social science and law. In 1865,1868,1875,1877, and 1881, Lamar was elected by the state legislature to represent Mississippi in the U. S. Senate from 1877 to 1885. Lamar was an opponent of Reconstruction, and did not consider freedmen

Lamar (Amtrak station)
–
The Lamar station is a train station in Lamar, Colorado served by Amtrak. It is served by Amtraks Southwest Chief line and it was originally built in 1907 by the Atchison, Topeka and Santa Fe Railroad, after a long-standing feud between the railroad, and the founder of the former town of Blackwell. The current station is designed in a similar to that of Garden City station in Kansas.

Pierre Auger Observatory
–
In Earths atmosphere such particles interact with air nuclei and produce various other particles. These effect particles can be detected and measured and it is located in the western Mendoza Province, Argentina, near the Andes. Construction began in 2000, the observatory has been taking production-grade data since 2005 and was completed in 2008. The northern site was to be located in southeastern Colorado, United States and it also was to consist of water Cherenkov detectors and fluorescence telescopes, covering the area of 10,370 km2 —3.3 times larger than Auger South. Unfortunately, in late 2010 it was decided the US would not host the northern observatory and as of early 2011. The observatory was named after the French physicist Pierre Victor Auger, the project was proposed by Jim Cronin and Alan Watson in 1992. Today, more than 500 physicists from nearly 100 institutions around the world are collaborating to maintain and upgrade the site in Argentina and collect, the 15 participating countries shared the $50 million construction budget, each providing a small portion of the total cost. From outer space, ultra-high-energy cosmic rays reach Earth and these consist of single sub-atomic particles, each with energy levels beyond 1018 eV. When such a single particle reaches Earth atmosphere, it has its energy dissipated by creating billions of particles, electrons, photons and muons. These particles spread longitudinally, creating a moving plane of particles. Such an incident is called an air shower, passing through the atmosphere, this plane of particles creates UV light, invisible to the human eye, called the fluorescing effect, more or less in the pattern of straight lightning traces. These traces can be photographed at high speed by specialised telescopes, called Fluorescence Detectors, then, when the particles reach the Earths surface, they can be detected when they arrive in a water tank, where they cause visible blue light due to the Cherenkov effect. A sensitive photoelectric tube can catch these impacts, such a station is called a water Cherenkov Detector or tank. The Auger Observatory has both types of covering the same area, which allows for very precise measurements. When an air shower hits multiple Cherenkov Detectors on the ground, the longitudinal axis point can be determined from the densities in each affected ground station. Depending on the difference of impact places, the angle of the axis can be determined. Only when the axis would be vertical, all ground detectors register at the same moment in time. Cosmic rays were discovered in 1912 by Victor Hess and he measured a difference in ionisation at different heights, an indication of the atmospheric thinning of a single ray

United States Census Bureau
–
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureaus primary mission is conducting the U. S. Census every ten years, in addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, and the Current Population Survey, furthermore, economic and foreign trade indicators released by the federal government typically contain data produced by the Census Bureau. The Bureaus various censuses and surveys help allocate over $400 billion in federal funds every year and help states, local communities, the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States. The Census Bureau now conducts a population count every 10 years in years ending with a 0. Between censuses, the Census Bureau makes population estimates and projections, the Census Bureau is mandated with fulfilling these obligations, the collecting of statistics about the nation, its people, and economy. The Census Bureaus legal authority is codified in Title 13 of the United States Code, the Census Bureau also conducts surveys on behalf of various federal government and local government agencies on topics such as employment, crime, health, consumer expenditures, and housing. Within the bureau, these are known as surveys and are conducted perpetually between and during decennial population counts. The Census Bureau also conducts surveys of manufacturing, retail, service. Between 1790 and 1840, the census was taken by marshals of the judicial districts, the Census Act of 1840 established a central office which became known as the Census Office. Several acts followed that revised and authorized new censuses, typically at the 10-year intervals, in 1902, the temporary Census Office was moved under the Department of Interior, and in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor. The department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their role in the department. An act in 1920 changed the date and authorized manufacturing censuses every 2 years, in 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code, by law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year, the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are widely used. for data collection, the Census Bureau definition is pervasive. Title 13 of the U. S. Code establishes penalties for the disclosure of this information, all Census employees must sign an affidavit of non-disclosure prior to employment. The Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government, only after 72 years does the information collected become available to other agencies or the general public

Pueblo, Colorado
–
Pueblo /ˈpwɛbloʊ/ is a home rule municipality that is the county seat and the most populous city of Pueblo County, Colorado, United States. The population was 106,595 in 2010 census, making it the 267th most populous city in the United States, Pueblo is the heart of the Pueblo Metropolitan Statistical Area totaling over 160,000 people and an important part of the Front Range Urban Corridor. As of 2014, Pueblo is the city of the Pueblo-Cañon City combined statistical area totaling approximately 208,000 people. Pueblo is situated at the confluence of the Arkansas River and Fountain Creek,112 miles south of the Colorado State Capitol in Denver, the area is considered semi-arid desert land, with approximately 12 inches of precipitation annually. With its location in the Banana Belt, Pueblo tends to get less snow than the major cities in Colorado. Pueblo is one of the largest steel-producing cities in the United States, the Historic Arkansas River Project is a river walk in the Union Avenue Historic Commercial District, and shows the history of the devastating Pueblo Flood of 1921. Pueblo has the least expensive real estate of all major cities in Colorado. The median home price for homes on the market in Pueblo is $147,851 as of February 2013 and it is the sixth most affordable place to live in America as measured by the 2014 Cost of Living Index. Costs of housing, goods and services, utilities, transportation, groceries, Pueblo was listed by AARP in 2013 as one of the Best Places to Live in the USA. James Beckwourth, George Simpson, and other such as Mathew Kinkead. George married Juana Maria Suaso and lived there for a year or two before moving, however, Simpson had no title to the land. The adobe structures were built with the intention of settlement and trade next to the Arkansas River, about a dozen families lived there, trading with Native American tribes for hides, skins, livestock, as well as cultivated plants, and liquor. Evidence of this trade, as well as other utilitarian goods and they allegedly killed between fifteen and nineteen men, as well as captured two children and one woman. The trading post was abandoned after the raid, but it became important again between 1858 and 1859 during the Colorado Gold Rush of 1859, the current city of Pueblo represents the consolidation of four towns, Pueblo, South Pueblo, Central Pueblo, and Bessemer. Pueblo, South Pueblo, and Central Pueblo legally consolidated as the City of Pueblo between March 9 and April 6,1886. The consolidated city became an economic and social center of Colorado, and was home to important early Colorado families such as the Thatchers, the Ormans. One author crowed of Pueblo that the necessity exists no longer for Sharps rifles and these have been supplied by the plow and the mowing-machine. Steel emerged as a key industry very early, and in 1909 the city was considered the only town west of the Mississippi River

Arkansas River
–
The Arkansas River is a major tributary of the Mississippi River. It generally flows to the east and southeast as it traverses the US states of Colorado, Kansas, Oklahoma and it then flows east into the Midwest via Kansas, and finally into the South through Oklahoma and Arkansas. At 1,469 miles, it is the sixth-longest river in the United States, the second-longest tributary in the Mississippi–Missouri system, and its origin is in the Rocky Mountains in Lake County, Colorado, near Leadville. In 1859, placer gold discovered in the Leadville area brought thousands seeking to strike it rich, the Arkansas Rivers mouth is at Napoleon, Arkansas, and its drainage basin covers nearly 170,000 sq mi. In terms of volume, the river is smaller than the Missouri and Ohio Rivers. The Arkansas from its headwaters to the 100th meridian west formed part of the US-Mexico border from the Adams–Onís Treaty until the Texas Annexation or Treaty of Guadalupe Hidalgo, the Arkansas has three distinct sections in its long path through central North America. At its headwaters, the Arkansas runs as a steep fast-flowing mountain river through the Rockies in its narrow valley and this section supports extensive whitewater rafting, including The Numbers, Browns Canyon, and the Royal Gorge. At Cañon City, Colorado, the Arkansas River valley widens and flattens markedly, just west of Pueblo, Colorado, the river enters the Great Plains. Through the rest of Colorado, Kansas, and much of Oklahoma, it is a typical Great Plains riverway, with wide, shallow banks subject to seasonal flooding, tributaries include the Cimarron River and the Salt Fork Arkansas River. In eastern Oklahoma the river begins to widen further into a more contained consistent channel, the river valley then expands as it encounters much flatter land beginning just west of Little Rock, Arkansas. It continues eastward across the plains and forests of eastern Arkansas until it flows into the Mississippi River. Important cities along the Arkansas River include Pueblo, Colorado, Garden City, Kansas, Wichita, Kansas, Tulsa, Oklahoma, Fort Smith, Arkansas, and Little Rock, Arkansas. The I-40 bridge disaster of May 2002 took place on I-40s crossing of Kerr Reservoir on the Arkansas River near Webbers Falls, Oklahoma. The problems over the possession and use of Arkansas River water by Colorado, while Congress approved the Arkansas River Compact in 1949, the compact did not stop further disputes by the two states over water rights to the river. The Kansas-Oklahoma Arkansas River Basin Compact was created in 1965 to promote mutual consideration and it led to the Kansas-Oklahoma Arkansas River Commission, which was charged with administering the compact and reducing pollution. The compact was approved and implemented by states in 1970, and has been in force since then. Through Oklahoma and Arkansas, dams artificially deepen and widen the river to build it into a navigable body of water. Many nations of Native Americans lived near, or along, the 1, the first Europeans to see the river were members of the Spanish Coronado expedition on June 29,1541

Antipodes
–
In geography, the antipode of any place on Earth is the point on the Earths surface that is diametrically opposite to it. A pair of antipodes are two points that are antipodal /ænˈtɪpədəl/ to each other and are connected by a line running through the centre of the Earth. Such points are as far away from each other as possible, in the Northern Hemisphere, the Antipodes may be used to refer to Australia and New Zealand, and Antipodeans to their inhabitants. Geographically the antipodes of Britain and Ireland are in the Pacific Ocean and this gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipode of London at about 50°S 179°E. The antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, approximately 15% of land territory is antipodal to other land, representing approximately 4. 4% of the Earths surface. The antipode of any place on the Earth is the place that is diametrically opposite it, so a line drawn from the one to the passes through the centre of the Earth. For example, the antipodes of New Zealands lower North Island lie in Spain, most of the Earths land surfaces have ocean at their antipodes, this being a consequence of most land being in the land hemisphere. The singular antipode is a back-formation from the plural antipodes, which in Greek is the plural of the singular antipous, sunrise and sunset do not quite oppose each other at antipodes due to refraction of sunlight. If the geographic coordinates of a point on the Earths surface are and this relation holds true whether the Earth is approximated as a perfect sphere or as a reference ellipsoid. For example, the antipode of the point in China at 37° N 119° E is the point in Argentina at 37° S 61° W, the word antipodes comes from the Greek, ἀντίποδες, plural of antipous, with feet opposite, from anti- opposed and pous foot. Medieval illustrations imagine them in some way inverted, with their growing out of their heads. From the time of St Augustine, the Christian church was skeptical of the notion. In 748, in reply to a letter from Saint Boniface, Pope Zachary declared the belief that beneath the earth there was another world and other men, another sun, in his letter, Boniface had apparently maintained that Vergilius of Salzburg held such a belief. The antipodes being an attribute of a spherical Earth, some ancient authors used their perceived absurdity as an argument for a flat Earth and this posed the problem that Christ told the apostles to evangelize all mankind, with regard to the unreachable antipodes, this would have been impossible. Christ would either have appeared a second time, in the antipodes, such an argument was forwarded by the Spanish theologian Alonso Tostado as late as the 15th century and St. Augustine doubts was a response to Columbuss proposal to sail westwards to the Indies. The author of the Norwegian book Konungs Skuggsjá, from around 1250 and he notes that they will see the sun in the north in the middle of the day and that they will have seasons opposite those of the Northern Hemisphere. The earliest surviving account by a European who had visited the Southern Hemisphere is that of Marco Polo and he noted that it was impossible to see the star Polaris from there. The idea of dry land in the southern climes, the Terra Australis, was introduced by Ptolemy, there are no non-stop scheduled flights between any two antipodal locations by commercial airline service—or anything even close

Indian Ocean
–
The Indian Ocean is the third largest of the worlds oceanic divisions, covering 70,560,000 km2. It is bounded by Asia on the north, on the west by Africa, on the east by Australia, the Indian Ocean is known as Ratnākara, the mine of gems in ancient Sanskrit literature, and as Hind Mahāsāgar, in Hindi. The northernmost extent of the Indian Ocean is approximately 30° north in the Persian Gulf, the oceans continental shelves are narrow, averaging 200 kilometres in width. An exception is found off Australias western coast, where the width exceeds 1,000 kilometres. The average depth of the ocean is 3,890 m and its deepest point is Diamantina Deep in Diamantina Trench, at 8,047 m deep, Sunda Trench has a depth of 7, 258–7,725 m. North of 50° south latitude, 86% of the basin is covered by pelagic sediments. The remaining 14% is layered with terrigenous sediments, glacial outwash dominates the extreme southern latitudes. The major choke points include Bab el Mandeb, Strait of Hormuz, the Lombok Strait, the Strait of Malacca, the Indian Ocean is artificially connected to the Mediterranean Sea through the Suez Canal, which is accessible via the Red Sea. All of the Indian Ocean is in the Eastern Hemisphere and the centre of the Eastern Hemisphere is in this ocean, marginal seas, gulfs, bays and straits of the Indian Ocean include, The climate north of the equator is affected by a monsoon climate. Strong north-east winds blow from October until April, from May until October south, in the Arabian Sea the violent Monsoon brings rain to the Indian subcontinent. In the southern hemisphere, the winds are milder. When the monsoon winds change, cyclones sometimes strike the shores of the Arabian Sea, the Indian Ocean is the warmest ocean in the world. Long-term ocean temperature records show a rapid, continuous warming in the Indian Ocean, Indian Ocean warming is the largest among the tropical oceans, and about 3 times faster than the warming observed in the Pacific. Research indicates that human induced greenhouse warming, and changes in the frequency, among the few large rivers flowing into the Indian Ocean are the Zambezi, Shatt al-Arab, Indus, Godavari, Krishna, Narmada, Ganges, Brahmaputra, Jubba and Irrawaddy River. The oceans currents are controlled by the monsoon. Two large gyres, one in the northern hemisphere flowing clockwise and one south of the equator moving anticlockwise, during the winter monsoon, however, currents in the north are reversed. Deep water circulation is controlled primarily by inflows from the Atlantic Ocean, the Red Sea, north of 20° south latitude the minimum surface temperature is 22 °C, exceeding 28 °C to the east. Southward of 40° south latitude, temperatures drop quickly, surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

1890 United States Census
–
The Eleventh United States Census was taken beginning June 2,1890. The data was tabulated by machine for the first time, the data reported that the distribution of the population had resulted in the disappearance of the American frontier. Data was entered on a machine readable medium, punched cards, the total population of 62,947,714, the family, or rough, count, was announced after only six weeks of processing. The public reaction to this tabulation was disbelief, as it was believed that the right answer was at least 75,000,000. The United States census of 1890 showed a total of 248,253 Native Americans living in America, down from 400,764 Native Americans identified in the census of 1850. The 1890 census announced that the region of the United States no longer existed. Up to and including the 1880 census, the country had a frontier of settlement, by 1890, isolated bodies of settlement had broken into the unsettled area to the extent that there was hardly a frontier line. This prompted Frederick Jackson Turner to develop his Frontier Thesis, the original data for the 1890 Census is no longer available. Almost all the schedules were damaged in a fire in the basement of the Commerce Building in Washington. Some 25% of the materials were presumed destroyed and another 50% damaged by smoke, the damage to the records led to an outcry for a permanent National Archives. The Librarian was asked by the Bureau to identify any records which should be retained for historical purposes, congress authorized destruction of that list of records on February 21,1933, and the surviving original 1890 census records were destroyed by government order by 1934 or 1935. The other censuses for which information has been lost are the 1800 and 1810 enumerations. Mayo-Smith, Richmond, The Eleventh Census of the United States

The Northeast grew by 2,785,149, the Midwest by 4,724,144, the results of the census are used to determine how many congressional districts each state is apportioned. Congress defines the formula, in accordance with Title 2 of the U. S. Code, each member of the House represents a population of about 647,000. The populations of the District of Columbia and Puerto Rico are excluded from the apportionment population because they do not have voting seats in the U.

Census
–
A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population, the term is used mostly in connection with national population and housing censuses, other common censuses include agriculture, business, and traffic censuses. United Nations recommendations also cover census topics to be collected, official definitions, classifications, the word is of Latin origin, during the Roman Republic, the census was a list that kept track of all adult males fit for military service. Current administrative data systems allow for other approaches to enumeration with the level of detail but raise concerns about privacy. A census can be contrasted with sampling in which information is obtained only from a subset of a population, typically main population estimates are updated by such intercensal estimates. Modern census data are used for research, business marketing, and planning. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling, similarly, stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official used to apportion the number of elected representatives to regions. In many cases, a carefully chosen random sample can provide accurate information than attempts to get a population census. A census is often construed as the opposite of a sample as its intent is to count everyone in a rather than a fraction. However, population censuses rely on a frame to count the population. This is the way to be sure that everyone has been included as otherwise those not responding would not be followed up on. The fundamental premise of a census is that the population is not known, the use of a sampling frame is counterintuitive as it suggests that the population size is already known. However, a census is also used to collect data on the individuals in the nation. This process of sampling marks the difference between historical census, which was a house to house process or the product of a decree. The sampling frame used by census is almost always an address register, thus it is not known if there is anyone resident or how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, a particular problem is what are termed communal establishments which category includes student residences, religious orders, homes for the elderly, people in prisons etc

Population density
–
Population density is a measurement of population per unit area or unit volume, it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans and it is a key geographical term. Population density is population divided by land area or water volume. Low densities may cause a vortex and lead to further reduced fertility. This is called the Allee effect after the scientist who identified it, commonly this may be calculated for a county, city, country, another territory, or the entire world. The worlds population is around 7,000,000,000, therefore, the worldwide human population density is around 7,000,000,000 ÷510,000,000 =13.7 per km2. If only the Earths land area of 150,000,000 km2 is taken into account and this includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to over 50 people per km2, thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states, microstates, cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo, for instance, Milwaukee has a greater population density when just the inner city is measured, and the surrounding suburbs excluded. Arithmetic density, The total number of people / area of land, physiological density, The total population / area of arable land. Agricultural density, The total rural population / area of arable land, residential density, The number of people living in an urban area / area of residential land. Urban density, The number of people inhabiting an urban area / total area of urban land, ecological optimum, The density of population that can be supported by the natural resources. S.
